地质统计学在复杂矿床开发中的应用——以布丘克金矿床为例

Application of geostatistics in the development of complex ore deposit——Take Buchuk Gold Deposit for example

中国现行的固体矿产勘查规范将矿床勘查类型分成3类,最为复杂的是第Ⅲ类型,该类矿床矿体形态复杂,产状不稳定,一定网度的勘查工程无法对矿体进行有效圈定,矿床的勘探和开发,都具有一定的局限性,往往是边探边采,不能进行大规模开发利用,不利于统一规划,矿床开发和环境保护不能兼顾。以布丘克金矿床为例,提出对此类矿床进行整体开发的思路,运用地质统计学的方法确定矿体的空间赋存状态,为这类矿床的开发提供了可行性的实践。

Deposit exploration is divided into three types according to China＇s current solid mineral exploration norms,among which Type Ⅲ is the most complex one. The deposits categorized in this type has complex morphology and variable occurrence,so that exploration projects with certain net dimension can not effectively delineate orebodies and the prospecting and development of deposits are constrained. Prospecting and mining usually are conducted simultaneously. Large-scale development can not be available as well as a comprehensive planning. And the project is not able to take care of both deposit development and environmental protection. The paper takes Buchuk Gold Deposit as the research subject,puts forward the development plan of this type of deposits as a whole,and determines the spatial occurrence of the orebody using geostatistics. The study explores the feasibility for developing similar deposits.
